Any 944 lux or 924S track dayers /racers on here?

[Lizard]

Few questions-

-Do you run additional oil coolers? or just the regular oil/water jobbie.

-Anyone really fettled a 2.5 power wise, have chatted to emc more power is posible but tough to achive it seems.

-Weight wise what have you got down to?

Cheers.

Intriguing questions - are you planning to race one? []

944man is the source of all wisdom in these things - he will be along shortly to provide the definitive answer

very hard to get it under 1000 kilos - afaik one of the 924S sprint cars was running around that weight. EMC are probably your best bet to extract some more power. Best bet is to drop a 968 lump in...

btw - welcome to the forum []

Hi Alex,

Yep, I've got a 924S, and since I got it for the express purpose of learning about handling, I do the odd track day, when I can.

Weight is definitely the way to go, rear seats, hood, sunroof, smaller wheels, lighter brakes and a plastic rear hatch make the world of difference.

Power, well, having looked at costs of a cam and TBs for the 8v, it seemed more sensible to fit a 3 litre 16 valve in there.

Oil cooling should be fine as standard, mine certainly was over many dozens track days. I can't agree more that weight removal is the way to go for more fun. I wouldn't bother much with the engine internals bar making sure it is outputting what it should - one of the joys of 944 budget trackday cars is you know you can drop a replacement engine in cheaply, to spend a few thousand extracting say 20% more is almost missing the point and arguably that money is better spent on an S2 or Turbo.

 

[Suffolk944]

Just out of interest what sort of money is involved in transplanting an S2 engine into a 924 ?

Cheers for that fellas.

Is primarily ment to be a very cheap track toy not a racer, but do have in mind doing a round or two of the MSA trackday Throphy that a few pals have done.

Is a 924s that emc popped a recon 944 lump in, so has tad more 944 power rather than early 924s, is an as new engine done 3k miles!

I do like the fact that if the engine goes pop 200-300 quid on ebay finds quite a few.

Also has 924 race Ledas & a full cage & is a really solid car, track car scuffs but not a rust spec in the normal places.

I've owned a fair few 944s in my times but other than on the turbos never fiddled power wise on the lux or s2, for what im planning an s2 would indeed be a better option, but this was such a cracking price & a great spec I couldnt resist, an s2 to this spec would be significantly more & much higher running costs.

Budget & reliabilty is key to this one, but lack of pace from such little power is a concern, last car I had with 160bhp was my Caterham & that was 557kg wet [] the car is still full fat trim & cage is heavy so naturally plexi rear hatch & grp bonnet is on the cards.

Im used to relitivly low power track cars- have played about a lot with track mk1 & 2 Golfs for years- (I leave one at the 'ring) with similar prehistoric Bosch injection & the gains can be very significant for a very small outlay as in my current car went 140bhp- 170bhp for 300-400 quid area, my last one ran at 190bhp & iok was more to achive but not silly money & still basic injection.

So im looking at a few budget options 185/190bhp has been achived on a v well set up emc 944, stock injection etc, so more is posible & would make it a tad more entertaining.

I saw that advert, looked a very nice car. Fwiw the 1988 model had the same HP as the 944

Apologies to OP for off topic..Depends a lot on how much you can do yourself. Had I done it myself, I'd have probably dropped a nut into the inlet port just before starting the finished engine, so in my case a lot []

I'd say without frills, £3-£5k plus two donor wrecks. I mean pre-loved, cherished examples of Stuttgart's/Ingolstadt's/Neckarsulm's finest.

If you start being fancy with Vitesse MAFs and built heads, double that figure.

 

[944 man]

I can advise you on how to lose weight, but Neil is better qualified to tell you what weighs what, because he weighed everything very carefully.

I have a stripped 944 series one track car and Im about to transfer the light parts onto a 150bhp 924S, but I haven't actually done anything yet. I will remove: both front seats and the rear seat back (fronts replaced with composite items) - door glass and side glass (replaced with polycarbonate) - rear wiper mechanism - rear hatch (replaced with polycarbonate) - electric window regulators (windows fixed in position) - door cards handles and bins (replaced with sheet, either plastic or alloy) - radio & speakers - electric hatch release (replaced with a T-pull) - electric sunroof mechanism - spare wheel, jack and tools - carpets & sound deadening (replaced with very lightweight carpet material) - rear seat belts and passenger side inertia reel belt - battery (replaced with a lightweight racing battery <10kgs!) - steel bonnet (replaced with a lightweight GRP part) - steel front wings (replaced with GRP parts, much lighter as a result of their not being undersealed). Im considering a polycarbonate windscreen although Im not sure how secure it as it wont be formed. Im also considering GRP doors (or gutting the existing doors) if a front cage is fitted.

I'm sure if anyone can get good power from a NA 944 it'll be EMC. The local garage I used many years ago (who ran several non porsche race cars) did some headwork as well experimentation with the exhaust etc and to be honest we gained very little power. However I really wouldn't worry about that straight away, if you get some weight out of the car and make sure it has good tyres, brakes and suspension I suspect you'll find it much quicker than the figures would suggest.

As for the engine swap costings, I agree with Sean (although my bill was rather higher, but then it was a completely flawless job), the job sheet for my car ran to something like 6 pages IIRC (I don't look back at the paperwork very often for obvious reasons).

 

[944 man]

Peter cant look back at the bills, as theyre doubtless hidden away from his wife! []

Ah well thats is indeed what they say, euro cars- '88 924s 160 bhp, was still however a slightly lower compression ratio to the early 944s & its 163 rating, but 1988 944s then shared that same number. however could run them on 91 octane, earlier cars should be run on 98/96

'87 924s 9.1:1 150
'84 944 10.6:1 163
'88 924s/944 10.2:1 160

All irrelevant in my cars case, depends what emc built it to.

Got to go now tho, this geeks anorak is too warm in this weather [] & sometimes you can never quite belive Porsche & their figures at all times, I mean a stock 968 with 240bhp ho ho ho dream on []

Hi,

On my 924S race car (Porsche Cup 1998/1999) I ran a large front mounted (protected) oil cooler.
Engine was skimmed (head) to increase compression and power + removed balance belts - about 170bhp max
Car was 1040kg (if I remember correctly) with lightweight bimpers, fibreglass wings and fibreglass (bendy) bonnet
All original glass retained. Did just under 1:20 round Castle Combe in 1999 (I estimate a road going 924S would be about 1:35).

Regards,
Andrew

I found on my S2 that if i ran for long periods of time,[on track], ie over 30mins at full chat the oil pressure would dip slightly.
To overcome this i was going to fit a 968 oil cooler as they are larger .
Or you can do a twin cooler set up, as per a Tiptronic car, ie a cooler in either corner.Just get a tiptronic cooler + get some pipes fabricated...
I never got round to it though, as i soon after bought a 968...

All the part weights are for a 1990 S2 except the leather seats which came from an 86 turbo.

I wanted to remove the balance belt (without machining or removing the shaft, initially) and I was told that the oil pickup pipe regularly fractured as a result. What did you do to avoid this / did you experience similar trouble / are you aware of it happening to others and in what circumstances / whats your opinion on the matter?

The only significant differences, off the top of my head, will be the seats, which weigh about 10kgs less in early cars / 924Ss and the dashboard, which weighs next to nothing.
